ORANGE COUNTY, N.C. (FOX News) - A Republican party headquarters in North Carolina was firebombed and a nearby building was vandalized and those responsible were still on the loose, authorities said Sunday.

The Charlotte Observer reported that the inside of the Orange County Republican Party headquarters in Hillsborough was severely damaged from the attack Saturday and an adjacent building was marked with spray pained graffiti reading “Nazi Republicans get out of town or else.” No one was injured.

The walls over the multi-room office were covered in black char, and a couch against a wall had been burned down to its springs. Shattered glass covered the floor, and a melted campaign yard signs showed warped lettering. According to WNCN-TV, a bottle of flammable liquid was thrown through the front window of the office.
